I have a combi boiler and hardly any hot water is coming out of taps ?

sounds like a glowworm swiftflow they rattle like they have gravel inside on hw demand after initial release of water pressure they trickle due to the heat exchanger being scaled up. if its a fair age mind you. otherwise check taps if only one tap then sus tap. if newish ignore this
